Leo Henken fd01d15d14 Fix test_novnc to adequately validate websocket upgrade ... Currently, test_novnc validates the websocket upgrade by verifying that the websocket response reports a protocol switch and that the response includes a server name specified in the configuration field vnc_server_header. This explicit server name configuration field introduces a security concern and convolutes the code base. HTTP RFC7231 (https://tools.ietf.org/html/rfc7231) section 6.2.2 says that when switching protocols, the response "MUST generate an Upgrade header field that indicates which protocols will be switched to". This patchset uses this required Upgrade field to validate the websocket upgrade instead of an environment-based configuration field, making the code base cleaner, safer, and more reliable. vnc_server_header is deprecated and necessary release notes are created.
